I'm still battling with the last two of these (plus the final puzzle). Beginning to wonder if I've done something wrong.
33a: This OD possibly leads to creation of death roll (6)
I think it will start with P and end with L and the wordplay should result in an extra letter as well
36a Market spicy sauce mostly to go on top of enchiladas (4)
Starts with N and also leads to an extra letter
